结构件，设置于壳体内，结构件的前端临近第一送风口的下部使得结构件与蜗舌共同限定出一出风风道，并且出风风道临近第一送风口处的内壁为过流截面沿气流方向逐渐变小的渐缩状；和
导流件，设置在出风风道内并与其渐缩部分限定出一出风间隙，导流件用于将气流导向出风间隙，以使气流在出风风道内壁的引导下，逐渐向气流中心方向聚合地吹出第一送风口。
可选地，导流件的外表面包括：
外端面，朝向第一送风口；和
导风面，从外端面的边缘沿远离第一送风口的方向并朝第一送风口的中心轴线方向倾斜延伸。
可选地，蜗舌和结构件配置成使出风间隙底部区段气流的上扬角度大于 其顶部区段气流的下倾角度，以便出风间隙底部区段的气流带动其余区段的气流共同朝前上方上扬流动。
可选地，蜗舌沿壳体的长度方向设置，前端大致水平；
结构件沿壳体的长度方向设置，具有由后向前逐渐向上弯曲的弧形表面。
可选地，壁挂式空调室内机还包括：
蜗壳，形成于壳体内，位于蜗舌的后方，与蜗舌限定出一主风道；
换热器，设置于壳体内，主风道配置成进口朝向换热器，出口连通出风风道，使得经换热器换热的气流经主风道、出风风道到达第一送风口。
可选地，壳体的前侧下部开设有第二送风口；

本发明的壁挂式空调室内机中，通过设置蜗舌和结构件，并将蜗舌的前端和结构件的前端分别延伸至临近第一送风口，使结构件和蜗舌之间限定出一出风风道，并且出风风道的临近第一送风口处的内壁为过流截面沿气流方向逐渐变小的渐缩状，使过流截面沿气流方向逐渐变小。并且，出风风道内部的导流件与出风风道的内壁渐缩部分限定出了一个出风间隙。如此一来，进入出风风道的气流(换热气流、新风气流等)向前流动的过程中，将在导 流件引导下将吹向出风风道内壁，最终流至出风间隙内。由于出风间隙的出风截面更小，使得其出风速度更高。高速气流在出风风道渐缩状内壁的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，使得该壁挂式空调室内机的送风距离更远，送风能力更强。
本发明的壁挂式空调室内机中，导流件不仅与出风风道内壁限定出了出风间隙，达到提升风速的作用，同时也恰好能将气流导向出风间隙，或者说是强迫气流朝出风间隙流动，以迫使气流接受渐缩状内壁的聚合引导，形成最终的聚合出风效果。本发明仅通过增设一结构件和一导流件就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。
进一步地，本发明的壁挂式空调室内机对导流件的外形进行了特别设计，使导流件包括外端面和导风面，倾斜延伸的导风面用于对气流进行引导，使气流更加平稳、顺畅地流动至出风风道内壁处，减少阻力损失。
进一步地，本发明的壁挂式空调室内机对出风风道形状进行设计，出风间隙底部区段气流的上扬角度大于顶部区段气流的下倾角度。由于气流上扬部分的上扬角度大于下沉部分的下倾角度，多股气流混合后的气流整体将上扬流动。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验。并且，气流上扬吹出也有利于提升其送风距离。
进一步地，本发明的壁挂式空调室内机还包括开设于壳体的前侧上部的第二送风口，并利用蜗壳与蜗舌限定出一主风道，使该壁挂式空调室内机具有多种出风形式，满足用户各种不同需求。
进一步地，本发明的壁挂式空调室内机的壳体前侧还设置了可移动的滑板，并在壳体前侧开设第二进风口，使得该壁挂式空调室内机的进风面积增大，更能有效利用换热器，且使得该壁挂式空调室内机的外观不单一，使产品与现有产品差异化。

具体实施方式
本发明实施例提供了一种壁挂式空调室内机100，为分体式空调器的室内部分，用于调节室内空气，例如制冷/制热、除湿、引入新风等等。
图1是根据本发明一个实施例的壁挂式空调室内机100的滑板70闭合时的前视示意图。图2是图1所示的壁挂式空调室内机100的滑板70开启时的前视示意图。图3是图1所示的壁挂式空调室内机100的滑板70开启时的侧视示意图。图4是图1所示的壁挂式空调室内机100的部分部件的***分解示意图。图5是图1所示的壁挂式空调室内机100的一种出风形式的示意图。图6是图1所示的壁挂式空调室内机100的另一种出风形式的示意图。图7是图1所示的壁挂式空调室内机100的又一种出风形式的示意图。
本发明实施例的壁挂式空调室内机100一般性地壳体10、蜗舌20、结构件22和导流件30。壳体10前侧开设有第一送风口11。第一送风口11用于将壳体10内的气流吹向室内，调节室内空气。前述的气流可为壁挂式空调室内机100在制冷模式下制取的冷风，在制热模式下制取的热风，或者在新风模式下引入的新风等。第一送风口11的数量可为一个，也可为多个。对应的，导流件30的数量可为一个，也可为多个。如图2所示，在壳体10的前侧沿壳体10的长度方向间隔开设有多个第一送风口11。第一送风口11可以是椭圆形、橄榄球形、长方形、正方形等，还可以在第一送风口11处配套设置横格栅、竖格栅、微孔形式等。壳体10上可设置有进风口，以允 许室内空气经进风口进入壳体10。如图4所示，壳体10可由前骨架101、后骨架102、侧盖板90(图4中仅示出一个)组合而成，并且在壳体10的前侧还可以设置前饰板103。蜗舌20设置于壳体10内，蜗舌20的前端延伸至临近第一送风口11的上部。结构件22设置于壳体10内，结构件22的前端临近第一送风口11的下部使得结构件22与蜗舌20共同限定出一出风风道(图中未标号)，并且出风风道临近第一送风口11处的内壁为过流截面沿气流方向逐渐变小的渐缩状。导流件30设置在出风风道内并与其渐缩部分限定出一出风间隙23，导流件30用于将气流导向出风间隙23，以使气流在出风风道内壁的引导下，逐渐向气流中心方向聚合地吹出第一送风口11。
本发明实施例的壁挂式空调室内机100中，通过设置蜗舌20和结构件22，并将蜗舌20的前端和结构件22的前端分别延伸至临近第一送风口11，使结构件22和蜗舌20之间限定出一出风风道，并且出风风道的临近第一送风口11处的内壁为过流截面沿气流方向逐渐变小的渐缩状，使过流截面沿气流方向逐渐变小。并且，出风风道内部的导流件30与出风风道的内壁渐缩部分限定出了一个出风间隙23。如此一来，进入出风风道的气流(换热气流、新风气流等)向前流动的过程中，将在导流件30引导下将吹向出风风道内壁，最终流至出风间隙23内。由于出风间隙23的出风截面更小，使得其出风速度更高。高速气流在出风风道渐缩状内壁的引导下，在向外流动过程中逐渐向气流中心方向聚合，形成汇聚效应，使得风力更加强劲，送风距离更远，使得该壁挂式空调室内机100的送风距离更远，送风能力更强。
本发明实施例的壁挂式空调室内机100中，导流件30不仅与出风风道内壁限定出了出风间隙23，达到提升风速的作用，同时也恰好能将气流导向出风间隙23，或者说是强迫气流朝出风间隙23流动，以迫使气流接受渐缩状内壁的聚合引导，形成最终的聚合出风效果。现有挂机中同样具有蜗舌，也就是说本发明可以仅通过增设一结构件22和一导流件30就实现了非常好的聚合送风效果，其结构非常简单，而且成本较低，易于实现量产推广，构思非常巧妙。
在一些实施例中，导流件30的外表面包括外端面31和导风面32。外端面31向第一送风口11，导风面32从外端面31的边缘沿远离第一送风口11的方向并朝第一送风口11的中心轴线方向倾斜延伸。本发明实施例的壁挂式空调室内机100对导流件30的外形进行了特别设计，使导流件30包括外 端面31和导风面32，倾斜延伸的导风面32用于对气流进行引导，使气流更加平稳、顺畅地流动至出风风道内壁处，减少阻力损失。
在一些实施例中，蜗舌20和结构件22配置成使出风间隙23底部区段气流的上扬角度大于其顶部区段气流的下倾角度，以便出风间隙23底部区段的气流带动其余区段的气流共同朝前上方上扬流动。本发明实施例的壁挂式空调室内机100对蜗舌20和结构件22的结构进行限定，使得出风风道形状满足出风间隙23底部区段气流的上扬角度大于顶部区段气流的下倾角度。由于气流上扬部分的上扬角度大于下沉部分的下倾角度，多股气流混合后的气流整体将上扬流动。在制冷模式时，上扬流动的冷风可充分避开人体，达到最高点后再向下散落，实现一种“淋浴式”制冷体验。并且，气流上扬吹出也有利于提升其送风距离。如图4和图5所示，蜗舌20沿壳体10的长度方向设置，前端大致水平；结构件22沿壳体10的长度方向设置，具有由后向前逐渐向上弯曲的弧形表面。也就是说出风间隙23顶部区段气流几乎不下倾，而出风间隙23底部区段气流会顺着弧形表面上扬，如此实现上扬出风。
参考图4和图5，壁挂式空调室内机100还包括蜗壳21和换热器50。蜗壳21形成于壳体10内，位于蜗舌20的后方，与蜗舌20限定出一主风道(图中未标号)。蜗壳21可以是集成在后骨架102上。换热器50设置于壳体10内，主风道配置成进口朝向换热器50，出口连通出风风道，使得经换热器50换热的气流经主风道、出风风道到达第一送风口11。本发明实施例的壁挂式空调室内机100的蜗舌20和蜗壳21的结构可以与现有挂机的蜗舌、蜗壳结构类似。通过设置蜗壳21与蜗舌20组成主风道，有利于将经换热器50换热后的气流经主风道引导至出风风道。
继续参考图5，壳体10的前侧下部开设有第二送风口12；主风道还配置成出口连通第二送风口12，使得经换热器50换热的气流经主风道到达第二送风口12。本发明实施例的壁挂式空调室内机100还包括开设于壳体10的前侧上部的第二送风口12，主风道连通出风风道和第二送风口12，使该壁挂式空调室内机100具有多种出风形式，满足用户各种不同需求，可以是仅经第一送风口11送风，还可以是仅经第二送风口12送风，也可以是同时经第一送风口11和第二送风口12送风。
在一些实施例中，壁挂式空调室内机100还包括：导风板40，可转动地 设置在第二送风口12处，用于调节主风道的气流流至第一送风口11和第二送风口12的比例以及用于调节第二送风口12的前后出风风向。如图5至图7所示，用箭头示出了导风板40处于不同角度时的气流流向。在图5中，导风板40水平设置，闭合第二送风口12，经换热器50换热的气流流经主风道、出风风道后全部流至第一送风口11处。在图6中，导风板40转动第一角度，导风板40的上端与蜗舌20之间具有较小的间隙，经换热器50换热的气流一大部分经主风道流至第二送风口12处，一小部分经主风道、出风风道流至第一送风口11处。在图7中，导风板40转动第二角度，导风板40的上端与蜗舌20之间具有较大的间隙，与图6的状态相比，此时流至第一送风口11的风量增加。通常，考虑到制冷时上扬出风更舒适，在制冷时优选采用图5所示的出风形式；在制热时下吹出风更舒适，在制热时优选采用图6所示的出风形式；在需要较远距离送风、较强劲出风、较大送风角度范围时可采用图7所示的出风形式，如此不同的出风形式对应不同需求，使得用户体验舒适性更佳。
如图4所示，本发明实施例的壁挂式空调室内机100还可包括多个摆叶41，可转动地设置在第二送风口12处，用于调节第二送风口12的左右出风风向。摆叶41的具体结构可以采用现有技术中可以实现左右出风风向调节的结构，在此不进行详述。
参考图1至图5，在壳体10的顶部开设有第一进风口13，前侧开设有第二进风口14。壁挂式空调室内机100还可包括滑板70，可移动地设置于壳体10的前侧，用于开闭第一送风口11和第二进风口14。在一些实施例中，第一送风口11位于第二进风口14的下方；滑板70配置成向前向上移动时，使第一送风口11暴露并且与壳体10之间形成进风间隙72来实现经第二进风口14进风。换热器50一般包括弯折连接的第一换热段51、第二换热段52和第三换热段53。通过设置滑板70在实现外观差异化的同时，也能增加有效进风面积。根据仿真和实测可知，第一换热段51属于高速区，由于传统挂机的前面板影响，导致传统挂机的进风空间受限，可利用的进风少，进风效率较低。本发明实施例的壁挂式空调室内机100中在前骨架101的前侧设置了滑板70，通过将滑板70向前向上移动，使得滑板70与前骨架101之间限定出进风间隙72，使前骨架101的前侧的第二进风口14也可进风，这样就可满足大进风需求，同时经第二进风口14进入壳体10内的气流使得 可以更有效利用第一换热段51，提高换热器50的换热效率。滑板70可以是依靠驱动机构(图中未示出)实现移动，在侧盖板90上沿上下方向可以设置有限位杆71，来限定滑板70的移动方向和支撑滑板70。
如图4和图5所示，壁挂式空调室内机100还包括贯流风机60，安装于壳体10内且位于换热器50的前方，用于促使室内空气经第一进风口13和第二进风口14进入壳体10，使其与换热器50完成换热，再将气流吹送至主风道。此外，在壁挂式空调室内机100还可以设置电加热器80。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
